Configure package repository
============================

You will need to configure your system to register with and trust packages
from the CrateDB package repository::

# Install prerequisites.
yum install sudo

# Import the public GPG key for verifying the package signatures.
sudo rpm --import https://cdn.crate.io/downloads/yum/RPM-GPG-KEY-crate

# Register with the CrateDB package repository.
sudo rpm -Uvh https://cdn.crate.io/downloads/yum/7/x86_64/crate-release-7.0-1.x86_64.rpm

The command above will install the ``/etc/yum.repos.d/crate.repo`` package
repository configuration file.
To register with the CrateDB package repository, create a file called ``cratedb.repo``
in the ``/etc/yum.repos.d/`` directory for RedHat based distributions, or in the
``/etc/zypp/repos.d/`` directory for OpenSuSE based distributions, containing::

Those two parameters have not been part of the previous package repository configuration. They are now inherited from the advised package repository configuration like ES is doing it.

We did not research about their meaning yet, please advise correspondingly if you think they should be removed again.

On our tests, they didn't cause any harm, so we just followed ES here, and included them to the new configuration.

.. NOTE::

CrateDB provides both *stable release* and *testing release* channels. You
can read more about the `release workflow`_.
The configured repository is disabled by default. This eliminates the
possibility of accidentally upgrading CrateDB when upgrading the rest
of the system. Each install or upgrade command must explicitly enable
the repository as indicated in the sample installation command below.

By default, yum_ (Red Hat's package manager) will use the stable
repository. This is because the testing repository is disabled.
If you would like to enable the testing repository, edit the ``crate.repo``
file and set ``enabled=1`` within the ``[crate-testing]`` section.

Install CrateDB
===============

With everything set up, you can install CrateDB::

sudo yum install crate
sudo dnf install --enablerepo=cratedb-ce-stable crate

.. TIP::

On older Red Hat and CentOS installations, please use the ``yum`` command
instead of ``dnf``. On SUSE based installations, please use the ``zypper``
command.

Trust signing key
=================

In order to trust the package signing key upfront, before being prompted
to do it on the first installation of CrateDB, you can also import it
into your repository keyring, like that::

# Install prerequisites.
yum install sudo

# Import the public GPG key for verifying the package signatures.
sudo rpm --import https://cdn.crate.io/downloads/yum/RPM-GPG-KEY-crate
